product Strong focusing and the radiofrequency quadrupole accelerator

The open-quote open-quote New Problems close-quote close-quote department presents novel problems for use in undergraduate physics courses beyond the introductory level. In this article the problems and solutions use basic principles of electromagnetism to explain strong-focusing accelerator known as the radiofrequency quadrupole. Their solutions use Laplace close-quote s equation and require the extraction of information from boundary conditions. They also introduce the quasistatic approximation and show how under appropriate conditions Laplace close-quote s equation can be used to solve time-dependent problems. The problems are suitable for a course in electromagnetism and may be of interest for a cours in classical mechanics
